1. What is the main characteristic of cystic fibrosis?

• A. Multiple upper respiratory infections
• B. An underproduction of exocrine glands
• C. Excessive, thick mucus
• D. An overproduction of thin mucus

Correct answer: C

Rationale: The main characteristic of cystic fibrosis is the production of excessive, thick mucus. This thick mucus leads to blockages in the airways, digestive system, and other organs. Choice A is incorrect because while individuals with cystic fibrosis are more prone to respiratory infections, the main characteristic is the mucus production. Choice B is incorrect as cystic fibrosis is characterized by the overproduction, not underproduction, of exocrine glands. Choice D is also incorrect as the mucus produced in cystic fibrosis is thick, not thin.

2. Which individual has the highest risk for developing skin cancer?

• A. A 16-year-old dark-skinned female who tans in tanning beds once a week.
• B. A 65-year-old fair-skinned male who is a construction worker
• C. A 25-year-old dark-skinned male whose mother had skin cancer.
• D. A 70-year-old fair-skinned female who works as a secretary.

Correct answer: B

Rationale: The correct answer is B, a 65-year-old fair-skinned male who is a construction worker. Fair-skinned individuals are at higher risk of developing skin cancer due to prolonged sun exposure. Construction workers are often exposed to the sun for long periods, further increasing the risk. Choices A, C, and D are less likely to develop skin cancer compared to choice B due to factors such as age, frequency of tanning bed use, and occupation.

3. A client with peptic ulcer disease is prescribed sucralfate. What is the mechanism of action of this medication?

• A. Neutralizes stomach acid
• B. Decreases gastric acid secretion
• C. Covers the ulcer site and protects it from acid
• D. Improves gastric motility

Correct answer: C

Rationale: The correct answer is C: Covers the ulcer site and protects it from acid. Sucralfate works by forming a protective barrier over ulcers, shielding them from stomach acid and promoting healing. Choice A, neutralizing stomach acid, is incorrect as sucralfate does not neutralize acid but acts as a physical barrier. Choice B, decreasing gastric acid secretion, is not the mechanism of action of sucralfate. Choice D, improving gastric motility, is unrelated to sucralfate's action on peptic ulcers.

4. A client with a spinal cord injury at the level of T1 is at risk for autonomic dysreflexia. Which symptom is indicative of this condition?

• A. Hypotension
• B. Tachycardia
• C. Severe headache
• D. Flushed skin below the level of injury

Correct answer: C

Rationale: Corrected Rationale: Autonomic dysreflexia is a condition commonly seen in clients with spinal cord injuries at T6 or above. It is characterized by a sudden onset of severe hypertension, pounding headache, profuse sweating, nasal congestion, and flushing of the skin above the level of injury. The severe headache is a key symptom resulting from uncontrolled hypertension. Choices A, B, and D are incorrect as autonomic dysreflexia typically presents with hypertension, not hypotension, tachycardia, or flushed skin below the level of injury.

5. A client with hyperkalemia is being treated in the emergency department. Which medication should the nurse prepare to administer?

• A. Potassium chloride
• B. Calcium gluconate
• C. Magnesium sulfate
• D. Sodium bicarbonate

Correct answer: B

Rationale: The correct answer is B, Calcium gluconate. In hyperkalemia, where potassium levels are elevated, calcium gluconate is administered to stabilize the myocardial cell membrane and protect the heart from potential arrhythmias. Potassium chloride (choice A) would worsen the condition by further increasing potassium levels. Magnesium sulfate (choice C) is not the primary treatment for hyperkalemia. Sodium bicarbonate (choice D) is used in metabolic acidosis, not specifically for hyperkalemia.
